Ford brought a small fleet of intelligent vehicles to San Francisco to showcase a technology that the company expects will be mainstream in about five years, from most automakers.

Two Ford Focus cars and a Ford Expedition were equipped with a technology called Dedicated Short-Range Communications (DSRC), which basically serves as a car-to-car wireless connection that currently serves as a crash avoidance system in Ford's implementation, and as a wireless toll collection mechanism overseas. Eventually, it could even be used for entertainment purposes.

Although Ford demonstrated the technology in a parking lot outside of AT&T Park, the company isn't alone in developing the technology. Ford, General Motors, Nissan, Honda, Toyota, Volkswagen, Audi, Mercedes, Hyundai, and Kia are all working together, plus truck, bus, and motorcycle companies, said Mike Shulman, the technical leader in Ford's Active Safety Research and Innovation department.

"Next year, we're doing a model deployment in a city where there will be thousands of equipped vehicles and trucks and buses all sending out these messages, and then the goal in 2013 is to start a regulation that will require this on all vehicles. Then, maybe consumer electronics companies would start designing products that could be retrofitted onto existing cars, because everyone sees the potential," Shulman said.

"Maybe five years from now, cars will be equipped with this," Shulman added.
